Description
The T9431 Analogue Input Module provides eight isolated analogue input channels and measures input currents in the range of 0 mA to 24 mA. Each channel supplies both digital state and analogue data to the processor for process monitoring.
Each input features five configurable voltage bands, with eight distinct switching thresholds that allow hysteresis. This configuration supports line monitoring and diagnostics of field devices, ensuring high reliability and operational safety in industrial automation and control systems.
